This conducted energy can cause harmful interference to radio communications 
by two possible paths. First, the RF energy may be carried through electrical 
wiring to other devices also connected to the electrical wiring. Second, at 
frequencies below 30 MHZ, where wavelengths exceed 10 meters, long stretches of 
electrical wiring can act as an antenna, permitting the RF energy to be 
radiated over the airwaves. Due to low propagation loss at these frequencies, such 
radiated energy can cause interference to other services at considerable 
distances.
